How do I go about this

I had an individual send me a check and I deposited it and it posted to my DDA same day for $18,900 and then we did the job… so paid guys and for materials and so on. All together let’s say $11,000 was put out. 5 days later the money is taken from my account and it was showing in there previously. I go to the bank right away and they tell me that there is nothing they can do cause that check was written from a closed business account and Then got a copy of the check in the mail So I immediately filed a 10 day intent to lie. But that really hammered us and I feel like I’m getting jerked around here and then the lady that the check came from calls after she received the letter and she says that’s a fraudulent charge with a stolen check and idk what to believe and I certainly don’t want to go after someone if they are going through the same thing as me. On top of all that we’re doing a merger with a historical roofing company and now we look like a couple idiots I’m sure. I just thought as soon as it was deposited and funds hit the account it was good to go
